In order to protect
her three children, the No Doubt singer won't go into details about why the
couple decided to call it quits, but she does hint: “If I could, I would just
tell you everything, and you would just be in shock.”

“My
life was literally blown up into my face... I
literally was so sheltered and naïve, and that's a lot why I think I
got myself into so much trouble, in a way,” revealed the Used
To Love You singer.

Gwen now has shared custody of the couple's children
– Kingston, 9, Zuma, 7, and Apollo, 2 – and struggles with the fact that she now only sees them 50 percent of the time. “It's like, the most
unjust, unbelievable system,” the singer said. However, she said that time on her own gave her a chance to heal and that the “blessing” in it was that she
had time to be creative.

Not
knowing where to turn during her heartbreak, Gwen found herself channeling her pain into writing new music. Sitting down to reflect
on the situation the 46-year-old was inspired to write an honest and
candid album about her traumatic year. Once the floodgates opened the
star penned her first solo album in a decade, This Is What the Truth
Feels Like.

Gwen
may be moving on with her life but admits that some days are still
hard. “I'm not going to say I'm not still picking up the pieces and
every day isn't a challenge. I'm still in shock. But it's an awesome
time.”
